SAN DIEGO (AP) — Dallas Cowboys receiver Dez Bryant was diagnosed with patellar tendinitis in his right knee after he got hurt Monday during a joint practice session with the San Diego Chargers.
Bryant left the field after he slipped coming out of a break during a one-on-one drill, then had an MRI.
The Cowboys said Monday night the MRI "revealed no tear to a ligament or tendon." Bryant will be evaluated on a day-to-day basis. The team said no timetable has been set for his return to practice.
Dallas was already without a pair of Pro Bowl pass-catchers, receiver Miles Austin (hamstring) and tight end Jason Witten (spleen).
Receivers Andre Holmes and Donovan Kemp also left practice early Monday and had MRIs. The team said Holmes has a low back strain and is day-to-day, but had no update on Kemp's left knee.
Dallas (No. 16 in the AP Pro32) plays its next preseason game Saturday night at home against St. Louis. After practicing again with the Chargers on Tuesday, the Cowboys have a day off before a workout at Cowboys Stadium on Thursday.
Bryant caught two passes for 15 yards Saturday in the Cowboys' 28-20 loss to the Chargers.
Coach Jason Garrett said before the MRI results were revealed that he was hopeful "this injury is not too severe." He said Bryant, the third-year receiver, has been having an outstanding training camp.
Witten got hurt after taking a hit in the first preseason game Aug. 13.
Austin, who missed six games last season while dealing with injuries to both hamstrings, sat out both preseason games so far. He isn't expected to practice this week.
When Austin started dealing with hamstring issues a week into camp, the Cowboys said they planned to be careful with their top receiver. But they also said then they expected him to miss maybe only a week.
The rash of injuries means more time for Kevin Ogletree, who came to camp trying to earn the spot as the team's third receiver. Dwayne Harris is also getting more opportunities.
Undrafted rookie Cole Beasley had seven catches for 104 yards in the game against the Chargers.
Dallas opens the regular season Sept. 5 at the defending Super Bowl champion New York Giants.
