Lions coach Jim Schwartz would not say Monday whether tight end Brandon Pettigrew’s role could change possibly as more of a blocker than a receiver.

But Schwartz lauded Pettigrew’s blocking and his tough 17-yard catch late in Sunday’s 25-21 loss at Arizona while also addressing Pettigrew’s needs to do a better job catching balls in traffic.

“But there’s some tough catches in traffic that he’s made in the past” Schwartz said Monday. “He needs to get back to making some of those.

“Tight ends there’s always going to be contact and (on) a lot of those balls there was contact. Guys are jostling for position they’re getting hands on the ball. But our guy’s got to be stronger than their guy when it comes to that.

“And those are the things that he needs to bring to the offense because there’s not going to be very much clean-air production for a tight end.”

Pettigrew played 55 of 58 offensive snaps Fellow tight ends Joe Fauria and Tony Scheffler played only six and four snaps respectively. Schwartz said their lack of involvement was a function of the game’s situation.
