Hall suffered a torn Achilles tendon and will miss the rest of the season, a league source told NFL Network insider Jason La Canfora.
"He had a little bit of a hyperextension of his knee and it was getting a little tight," Lewis told reporters. "I think time will allow that to be fine."
Green came down awkwardly after the reception and was clearly in pain as he stayed down on one knee. He was eventually able to get to his feet, but wasn't able to put much weight on his right leg. Initially announced as probable to return, Green came back on the next series during the second quarter to run a 7-yard reverse. He then left again and was held out during the second half as a precaution, riding a stationary bike on the sideline.
"I just came down straight-legged and my knee buckled," Green said. "At halftime when I came in and sat down, it got real stiff. I couldn't really get any movement."
