For some players, life in the NFL is rough. As some athletes found out they were signed to the Pittsburgh Steelers' practice squad Sunday, four found out they were replaced on Monday.

It was announced Monday morning the team has signed TE Xavier Grimble, OT Matt Feiler, RB Fitzerald Toussiant and WR Isaiah Burse to their practice squad.

To make room for those players, the team released RB Dominique Brown, TE Harold Spears, OL Antonio Johnson and WR Jarrod West.

The Steelers could still very well make moves within the organization and the practice squad as more players become available. Two names to keep an eye on Monday are Anthony Chickillo and Doran Grant. The two 2015 draft picks of the Steelers were released Sunday when they signed RB Jordan Todman and DL Caushaud Lyons. The players have 24 hours to clear waivers and then could be signed by the Steelers for their practice squad.

The Steelers 10-player unit can, and most likely will, continue to change as more players become available.
