FOXBOROUGH — D.J. Williams is learning an awful lot about the Patriots’ offense. Now the tight end is hoping for a chance to put that knowledge to good use.
For the second time in two weeks, Williams has been signed because an injury to a tight end contributor has left the team thin at that position. On Nov. 27, it was not long after Michael Hoomanawanui was sidelined. Williams was signed, didn’t play in a game, then was released Dec. 4.
He’s back again, signed Monday, following a season-ending knee injury suffered the day before by Rob Gronkowski. Because of the severity — and because Hoomanawanui returned to practice only last week — Williams should be able to stick around a bit longer this time. The only other tight end on the roster is Matthew Mulligan, who has two catches on the season. Full story for BostonGlobe.com subscribers.
