Johnson (elbow) is scheduled to throw a simulated game Tuesday, Christopher Smith of MassLive.com reports.

EDGE Analysis

Johnson completed another bullpen session Saturday, clearing the way for him to face live hitters next week. The 28-year-old has been on the injured list since early April with left elbow inflammation, and seems likely to remain there for at least a few more weeks as he rebuilds his arm strength.

Johnson (elbow) is scheduled to throw a bullpen session with breaking balls Wednesday, freelance sports writer Maureen Mullen reports.

EDGE Analysis

Johnson tossed a 25-pitch bullpen session Sunday without issue, so he'll take the next step forward and mix in some breaking balls. While this is positive news for the reliever, the Red Sox still haven't released a timetable for his return.

Johnson threw a 25-pitch bullpen session and felt fine afterwards, Pete Abraham of The Boston Globe reports.

EDGE Analysis

Johnson was shut down in early April with elbow inflammation so this news is a step forward for Johnson. He threw only fastballs, meaning his return to the mound is still not close, though the worst fear of a torn elbow ligament seems to have been averted.

Johnson (elbow) will throw a bullpen session Sunday, Jen McCaffrey of The Athletic reports.

EDGE Analysis

The session will be Johnson's first since being shut down with elbow inflammation in early April. He's expected to throw only fastballs.

EDGE Analysis

Johnson has been sidelined since April 6 with elbow inflammation. While this is a step in the right direction for the southpaw, who resumed throwing earlier in the week, a timetable for his return likely won't emerge until Johnson is further along in his rehab.

Johnson (elbow) will play catch from 60 feet Tuesday, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Tuesday's throwing session will mark Johnson's first since being shut down with elbow inflammation earlier in the month. While this is an encouraging step for the southpaw, a timetable for his return likely won't emerge until he's further along in his throwing program.

Johnson's original diagnosis of left elbow inflammation was confirmed Monday after tests revealed no structural damage to his throwing arm, Chris Cotillo of MassLive.com reports.

EDGE Analysis

The Red Sox had been bracing for the worst after Johnson felt pain in the elbow while throwing a curveball in a disastrous relief appearance Friday in Arizona, but the 28-year-old was fortunate to avoid a season-ending injury. That said, Johnson is currently without a timetable to return from the 10-day injured list, though the Red Sox plan to meet with the lefty Tuesday to map out a rehab schedule for him. Boston brought up Marcus Walden from Triple-A Pawtucket over the weekend to replace Johnson in the bullpen.

Johnson was placed on the 10-day injured list Saturday with left elbow inflammation, Pete Abraham of The Boston Globe reports.

EDGE Analysis

He gave up seven runs over 1.1 innings Friday, so perhaps this explains why he was so ineffective. Right-hander Marcus Walden was recalled from Triple-A in a corresponding move.

Johnson allowed seven runs on six hits and a walk while striking out two over 1.1 innings in Friday's 15-8 loss to Arizona.

EDGE Analysis

Johnson's first three outings were encouraging as the left-hander showed increased velocity and was dominant. That all changed Friday when he needed 39 pitches to get four outs. That he was used so much may preclude Johnson from getting Sunday's spot start, although Friday's appearance may qualify as an in-between starts bullpen session. Either Johnson or Hector Velazquez or both will figure prominently in the series finale Sunday.

Johnson is likely to start Sunday's game against Arizona, Chris Cotillo of MassLive.com reports.

EDGE Analysis

In an effort to nab an extra day of rest for his starting rotation, manager Alex Cora is expected to give either Hector Velazquez or Johnson an opportunity for a spot start in the series finale. "Still waiting to see how it goes today," Cora said. "BJ most likely. We've still got Hector. They can go multiple innings. We'll see how it goes." If Johnson does end up pitching Sunday, Chris Sale would take the mound for Tuesday's home opener against the Blue Jays.
