As Dallas Cowboys coach Jason Garrett said Monday, no one can replace receiver Dez Bryant.
But the Cowboys have started the process of looking for some wide receiver depth with Bryant out at least the next six weeks with a fractured right foot that was surgically repaired Monday.
The Cowboys are working out four receivers Tuesday, including former New York Giants starter Hakeem Nicks.
Austin Pettis, Nick Toon and Clyde Gates will also workout for the Cowboys. Gates was among the Cowboys' final roster cuts two weeks ago.
Nicks, 27, spent his first five seasons with the Giants before playing in 2014 for Indianapolis.
