I know that Hoomanawanui was taken back to the locker room at some point yesterday. Not sure if he returned. My guess is he either goes on IR or is granted release.
He was only essential with Fells sidelined by his shin injury. With Fells back, BB might be willing to run their base 2 TE offense without a backup until Hernandez is back, if it means having a better 3 WR package, which the Pats lined up in for half the snaps yesterday, in the meantime. Meanwhile, even with three active TE's yesterday, the Pats only used a 3TE set 3 times.
When Hernandez is healthy, Fells goes back to his backup/3rd TE role, with the only remaining question being who goes when Shiancoe comes off the in-season IR?
