Jackson (elbow) was placed on the 60-day injured list Sunday with a torn UCL.

EDGE Analysis

Atlanta reported Saturday that an MRI showed damage to Jackson's UCL, but the extent of that damage was previously unclear. The right-hander may require Tommy John surgery, which would likely sideline him until the summer of 2023.

Jackson (forearm) recently underwent an MRI that revealed damage to his UCL.

EDGE Analysis

Jackson dealt with forearm tightness this week and was initially labeled as day-to-day, but it appears as though he'll be forced to miss significant time. UCL damage can often lead to Tommy John surgery, and the right-hander is undergoing a comprehensive evaluation process to determine his recovery process. It's possible that he'll be unavailable for most or all of the 2022 campaign following his diagnosis.

Jackson (forearm) completed a 10-pitch bullpen session Thursday, David O'Brien of The Athletic reports.

EDGE Analysis

The side session marks a step forward for Jackson after he missed a week of workouts at the start of camp due to forearm tightness, but manager Brian Snitker is still characterizing the right-hander as "day-to-day" as Opening Day nears. Atlanta hasn't yet ruled Jackson out from avoiding a trip to the injured list to begin the season, but he'll presumably need to advance to facing hitters within the next few days to have a shot at breaking camp as a member of the big club's bullpen.

Jackson is day-to-day with forearm tightness, Justin Toscano of The Atlanta Journal-Constitution reports.

EDGE Analysis

Forearm tightness can sometimes be the first sign of a very serious injury, though the fact that Jackson is merely considered day-to-day may suggest that this isn't one of those cases. While he's resumed throwing, the issue has so far prevented him from pitching in a Grapefruit League game, so it's possible he'll be forced to open the season on the injured list even if his forearm tightness proves to be relatively minor.

Atlanta activated Jackson from the paternity list Sunday.

EDGE Analysis

Jackson rejoins Atlanta's bullpen after going on paternity leave Thursday. The righty has impressed with a 1.50 ERA and 18:5 K:BB in his last 12 innings and could potentially pitch in some save situations if closer Will Smith continues to struggle.

Atlanta placed Jackson on the paternity list Thursday.

EDGE Analysis

The team will replace Jackson in the bullpen with Chris Martin (elbow), who was reinstated from the 10-day injured list in a corresponding move. Jackson will be away from Atlanta for 1-to-3 days to spend time with his newborn child, and he should rejoin the team at some point during its 10-game West Coast road trip that kicks off Friday.

Jackson (2-2) struck out three in 1.1 perfect innings to earn the win Tuesday versus Washington.

EDGE Analysis

The right-hander was able to limit the damage after Tyler Matzek allowed Washington to tie the game at 5-5 in the seventh inning. Jackson then became the pitcher of record as Atlanta retook the lead on an Ozzie Albies home run. Through 14.2 innings since the start of August, Jackson has given up two runs on nine hits and six walks while striking out 21. He's been excellent with a 2.05 ERA, 1.23 WHIP and 59:25 K:BB through 52.2 innings overall while adding 24 holds as a setup man to closer Will Smith.

Jackson gave up a hit and struck out two in a scoreless seventh inning during Thursday's win over the Phillies.

EDGE Analysis

The right-hander has rebounded in strong fashion from an awful 2020 season. Through 41 appearances and 35 innings this year, Jackson has posted a 2.06 ERA, 1.23 WHIP and 36:16 K:BB with a win and 12 holds. He's not likely to work his way back into the closer mix, but the 29-year-old has become a reliable setup man in front of Will Smith.

Jackson gave up a hit and struck out one without allowing an earned run in two-thirds of an inning Sunday, recording his sixth hold of the season in a win over the Marlins.

EDGE Analysis

He did allow two inherited runners to score after entering the game with two on and one out in the seventh inning, but they went on A.J. Minter's ledger. Jackson extended his scoreless streak to 12 appearances and 10.1 innings with the effort, and on the year he boasts a 1.11 ERA, 1.15 WHIP and 22:11 K:BB over 24.1 frames.

Jackson (1-1) took the loss Wednesday, allowing one run on one hit while striking out one in the seventh inning as Atlanta fell 4-1 to the Blue Jays.

EDGE Analysis

Entering the game with the score tied 1-1, Jackson's first pitch was launched over the center-field fence by Teoscar Hernandez. The right-hander has a strong 1.93 ERA through 14 innings to begin the season, but his 12:8 K:BB indicates he's been more lucky than good.
