Jackson was designated for assignment by the Blue Jays on Tuesday.

EDGE Analysis

Jackson was reinstated from the 10-day injured list Sunday after missing time with a lower-back injury, but even after firing three scoreless frames during Monday's clash, he's been designated for assignment. He possesses an 11.12 ERA and 2.19 WHIP with a 19:13 K:BB over 28.1 innings this season with Toronto.

The Blue Jays activated Jackson (back) from the 10-day injured list Sunday.

EDGE Analysis

The Blue Jays have set their rotation for the next two days, so the team's decision to activate Jackson suggests he'll be in line for a bullpen role initially in his return to action. Jackson should be available in Sunday's series finale with the Yankees for multiple innings in relief after the Blue Jays needed five bullpen members to cover the final seven frames of Saturday's 2-1 win after starter Clayton Richard (lat) departed following the second inning. Toronto will require a replacement in the rotation for Richard beginning on July 18 after the lefty was moved to the 10-day IL to clear room on the active roster for Jackson.

Jackson (back) joined Triple-A Buffalo to start a rehab assignment Wednesday, Ben Nicholson-Smith of Sportsnet.ca reports.

EDGE Analysis

Jackson landed on the injured list June 18 with the lower-back injury after giving up seven runs in his previous start. The 25-year-old may not return to the Blue Jays in a starting capacity, instead serving in a multi-inning role out of the bullpen.

Jackson (back) is throwing from a mound without issue, Alexis Brudnicki of MLB.com reports.

EDGE Analysis

It's not clear exactly where Jackson stands in his recovery, but things are going as planned so far. With him able to throw from a mound, a rehab assignment may not be far off.

Jackson was placed on the 10-day injured list Tuesday due to a lower-back injury, Scott Mitchell of TSN.ca reports.

EDGE Analysis

Jackson was tagged for seven runs during Monday's start against the Angels, though the back issue may have played a role in his poor showing. The Blue Jays have yet to issue a timetable for his return, but he'd miss just one turn through the rotation if he can return after the 10-day minimum.

Jackson (1-5) took the loss Monday as the Blue Jays were downed 10-5 by the Angels, surrendering seven runs on six hits -- including three home runs -- and two walks in only two-thirds of an inning. He failed to strike out a batter.

EDGE Analysis

After Derek Law turned in a perfect first inning as the Jays' opener, Jackson entered the game and served up a homer to Justin Upton on the first pitch he threw, setting the stage for an absolutely disastrous outing. The veteran right-hander came into Monday with a double-digit ERA and somehow made it worse, and he now sits with a 12.43 mark, and a mind-boggling 4.3 HR/9, through 25.1 innings. Toronto doesn't have a lot of options to replace Jackson, but even in a rebuilding season it seems inconceivable that they'd continue to send the 35-year-old to the mound every fifth day given his performance so far.

Jackson will work as the primary pitcher Monday against the Angels.

EDGE Analysis

Derek Law will serve as the opener in front of Jackson for a second straight week. The veteran right-hander picked up a win as the primary pitcher his last time out, allowing two runs on four hits and two walks while striking out two across five innings.

Jackson (1-4) allowed two earned runs on four hits and two walks while striking out two across five innings to earn the win Wednesday against the Orioles.

EDGE Analysis

Jackson took over in the second inning and worked with little trouble until losing his command in the fifth inning. He began the frame by walking the first two batters he faced and ultimately allowed a run to cross the plate on a wild pitch. Still, this was one of Jackson's better efforts of the season and the first time he's worked five innings since May 20 -- a span of three starts. Even with this performance, he has a 10.22 ERA and 2.03 WHIP across 24.2 innings for the season. He'll likely pitch again Monday against the Angels, though it remains to be seen if he works as a traditional starter or a primary pitcher.

Jackson will work as the primary pitcher Wednesday against the Orioles, Shi Davidi of Sportsnet.ca reports.

EDGE Analysis

Jackson was originally scheduled to start, but he'll instead follow an opener (Derek Law) in an effort to get him past the top of the order out of the gate. The veteran right-hander has made five starts for the Blue Jays this season, struggling to an 11.90 ERA, 2.24 WHIP and 15:8 K:BB in 19.2 innings of work.

Jackson is not starting Wednesday against the Orioles, Ben Nicholson-Smith of Sportsnet.ca reports.

EDGE Analysis

Jackson had been scheduled to take his turn in the rotation, but Derek Law will get the nod instead. Law hasn't pitched more than two innings in any appearance this season, so he's likely to be more of an opener than a true starter. Jackson hasn't reportedly been battling any injury, so it's possible he'll be available as a primary pitcher following Law. With an 11.90 ERA and a 2.24 WHIP in his five starts for the Blue Jays this season, it would hardly be a surprise for Jackson to permanently lose his spot in the rotation.
