EAST RUTHERFORD, N.J. (AP) — The New York Giants have had a hold-your-breath moment with rookie running back Saquon Barkley.

The No. 2 overall draft pick caught a swing pass out of the backfield from fellow rookie Kyle Lauletta during an indoor practice Monday and may have injured himself running down the sideline after the catch.

Barkley seemed to be favoring a leg as he walked back up the field. He eventually put his hands on his knees and then went to the turf and lay on his back while head trainer Ronnie Barnes examined him.

An ice pack was put on his left leg. However, it had been removed before he left the field after the roughly 70-minute practice, which was moved indoors by rain.

Coach Pat Shurmur could not shed any light on the injury. He did not appear worried.

Barkley had the perfect start to his Giants’ career in the 20-10 preseason loss to the Cleveland Browns on Thursday night. He took a handoff from Eli Manning on the first play from scrimmage and scampered 39 yards. The former Penn State running back finished with five carries for 43 yards.
