So, Thuney was injured and didn't finish yesterday, while Andrews is also nicked up? Solder also missed due to undisclosed reasons.
Although Karras has impressed, I still think we could add another IOL to the competition. Not a big name, but it's possible that a vet camp cut could be explored, unless someone else impresses.
Getting a decent vet camp cut seems unlikely to me. This was a very high-demand/short-supply year for IOL in free agency, and several guys got ++ contracts. So, I'm doubtful that teams will be letting any even halfway decent vet go at the end of their camps.
Also, it seems to me that the closer it gets to the regular season, the less interested the Pats would be in bringing in a guy who'd be brand new to the playbook, the OL calls, etc. If the injury to Thuney turns out to be serious, and the rest of the OL candidates in camp are actually dreck (difficult to say at this point), I don't think the Pats would wait until camp cuts from other teams.
However, with the way that the Pats trainers and medical staff have been managing guys with even relatively minor injuries since the disaster of 2015, I'm not ready to assume the worst every time a guy misses a day.
Anyway, Fleming has started and played full games for the Pats at both Guard spots. Jamil Douglas (6040/308) was a 2015 4th-round pick for the Fins, and started 6 games for them as a rookie. He's been in the Pats' system since last October, so he should be up-to-speed on the playbook and calls by now.
King, Croston or Jelks (NFI) could be PS depth for the IOL.
