Crawford (knee) threw an up-and-down bullpen session Tuesday and will report to extended spring training in Fort Myers on Thursday, MLB.com reports.

EDGE Analysis

Crawford will begin the process of pitching to hitters and starting in extended spring training games before embarking on a rehab assignment. The Red Sox estimate a June return at the earliest for the right-hander.

Crawford (knee) threw an "up-and-down" bullpen session Friday, Jen McCaffrey of The Athletic reports.

EDGE Analysis

Crawford's next step is expected to be a live batting practice session, which would be his first time facing hitters since he was diagnosed with right patellar tendinopathy. There is still no timetable for Crawford's return to the Boston rotation, but a rehab assignment shouldn't be too far off.

EDGE Analysis

EDGE Analysis

Crawford's recovery from right patellar tendiopathy seems to be coming along as expected, but the Red Sox are proceeding cautiously with him. The right-hander is able to throw off a mound but it's not clear when he might be ready to face hitters and go out on a rehab assignment.

The Red Sox placed Crawford on the 15-day injured list Thursday with right patellar tendiopathy, Mac Cerullo of the Boston Herald reports.

EDGE Analysis

Crawford's knee issue dates back to early last season, but he has resumed throwing off a mound. The right-hander is without a timeline to make his season debut, but he appears likely to miss at least the first month or so.

Crawford (knee) is scheduled to throw bullpen sessions Tuesday and Friday of next week, Jen McCaffrey of The Athletic reports.

EDGE Analysis

Crawford has thrown a few low-intensity bullpens this spring to avoid aggravating the knee, but next week's sessions will be at normal effort. Given the amount of time he'll need to build up, Crawford is expected to miss the start of the regular season and likely all of April.

Red Sox manager Alex Cora said Tuesday that Crawford (knee) is feeling better but has not progressed with his baseball activities, Mac Cerullo of the Boston Herald reports.

EDGE Analysis

Crawford will not be ready for Opening Day as he battles patellar tendon soreness and things look to be trending toward longer than a minimum stay on the 15-day injured list. Brayan Bello (shoulder) is also expected to begin the year on the IL but appears likely to rejoin Boston's rotation before Crawford.

EDGE Analysis

Per the same report, Brayan Bello (shoulder) and Lucas Giolito (elbow) are on track to be ready for the start of the season, which gives clarity for projecting Boston's rotation. Crawford is dealing with patellar tendon soreness and is unlikely to be able to build up in time. He seems likely to open the year on the 15-day injured list.

Manager Alex Cora said Saturday that Crawford (knee) isn't certain to be ready to pitch by Opening Day, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Crawford has been experiencing patellar tendon soreness and is consequently behind schedule, though he did throw a bullpen session Friday. Despite that mound session, it's unclear if the right-hander will be fully ramped up by the time the regular season starts. Per Cotillo, Cora said of Crawford, "With Kutter, that's the one it looks like is going to be long. Opening Day, right now, is an 'if.' Let's see what happens." The Red Sox are already dealing with rotation issues, as Brayan Bello is also behind schedule due to a shoulder injury.

Crawford (knee) threw a bullpen session Friday, Jen McCaffrey of The Athletic reports.

EDGE Analysis

Crawford has been eased into things early on in Red Sox camp as he tries to get past patellar tendon soreness, and it's a good sign that he's been cleared for mound work. The right-hander should have enough time to ramp up before Opening Day as he looks to lock down a rotation spot.
