Sources: MRI for Buccaneers' Mayfield shows low-grade sprain - ESPN

TAMPA, Fla. — The MRI for Tampa Bay Buccaneers quarterback Baker Mayfield revealed a low-grade AC joint sprain in his left shoulder but no additional damage, sources told ESPN's Jeremy Fowler on Monday.

An additional source told ESPN that the general feeling is that Mayfield is pretty fortunate to have not sustained a more serious injury.

Mayfield's status for Sunday's game against the Arizona Cardinals remains uncertain, but there are no long-term injury concerns.

Mayfield was injured in the Buccaneers' 34-7 loss to the Los Angeles Rams on Sunday night — their third straight loss, which dropped them to 6-5 this season.

After leading the Buccaneers on a touchdown drive late in the second quarter, Mayfield went into the medical tent on the Buccaneers' sideline. He was listed as questionable to return because of the injury but returned for Tampa Bay's next drive.

After attempting a long pass on the final play of the first half from the Tampa Bay 37-yard line with 5 seconds to go, Mayfield fell to the ground and appeared to be in pain again. He was labeled doubtful to return after halftime, then was ruled out later in the third quarter. He was seen on the sideline with his left arm in a sling.

He was replaced by Teddy Bridgewater, who would start for Tampa Bay if Mayfield, who has led the Bucs to two straight NFC South division titles, misses time.

Bowles said earlier Monday that losing Mayfield would be a «big loss because of the way he's been playing and carrying us the past few
