Packers HC Mike McCarthy Tuesday Presser: We'll know more tonight about Don Barclay's knee

From the moment Mike McCarthy took the podium for his Tuesday press conference, it was clear the Packers head coach was in a sour mood. Certainly, part of that was the result of the apparently serious injury suffered by offensive lineman Don Barclay. That was the topic of the first question McCarthy faced from the media.

• The only clarification McCarthy gave regarding Barclay's situation is that he suffered a knee injury during a team blitz drill. "[Barclay] got caught in a bad position. He's being evaluated. We'll know more tonight." Given that Barclay was expected to back up at right tackle, both guard spots, and possibly even center, a prolonged absence could have a major effect on the roster.
• When asked if Derek Sherrod could back up both offensive tackle spots, McCarthy responded, "Derek has really been working both. We don't lock in on one guy. Derek can move over to the right." Sherrod had previously only been discussed as a backup left tackle.
• The coach had high praise for undrafted rookie quarterback Chase Rettig. "I thought he did a nice job today. Ran the two-minute drill well." McCarthy also added, "I like where he is mentally. It's tough to get quarterback reps in this climate." Reports on Rettig during OTAs and minicamp were mixed, but he appears to have steadied himself in the second week of training camp.
• With Barclay out indefinitely, interior offensive lineman Lane Taylor will receive an extended look in practice. McCarthy wants to see improvement from the second-year blocker, "Lane Taylor is doing a lot of good things. He's been up and down. I'm looking for him to put together a good week of practice."
• McCarthy described safety Morgan Burnett's injury as an oblique strain, adding, "We'll know more this afternoon." Burnett's absence has given second-year defensive back Chris Banjo a chance to shine. According to McCarthy, "Chris Banjo looks a lot more confident. You've seen him play faster at the safety position. Important for him to take advantage."
