Wide receiver Chris Hubert catches a pass during rookie minicamp this past weekend.

For a second straight year, the Cardinals have mined their tryout players at rookie minicamp for a couple of worthy signings.

After three days of work over the weekend, the Cards decided to sign a pair of undrafted rookies – Idaho running back

Elijhaa Penny and Fayetteville State wide receiver Chris Hubert. Penny is a bigger back at 6-foot-2 and 234 pounds, and Hubert is a slot receiver at 5-9, 170.

Penny had 1,159 yards rushing and 10 touchdowns on 246 carries for Idaho last season. Hubert had 71 catches for 862 yards and 13 touchdowns.

To make room on the roster, the Cardinals release running back Jared Baker and outside linebacker Mike Reilly. Baker had just been signed as an undrafted rookie free agent last week.

It's the second straight season the Cardinals have signed multiple tryout players from rookie minicamp. Last season, all three made a push at the 53-man roster: quarterback Phillip Sims, safety Harold Jones-Quartey and safety Brandon Person. Person remains on the roster after getting hurt last season; Jones-Quartey was released but picked up on waivers by the Bears, with whom he played for last year.

Both Penny and Hubert join position groups within which it will be hard to find a spot. The Cardinals have depth at wide receiver, all the way down to 2015 practice squad returnee Jaxon Shipley, while the running back room already has proven players in David Johnson, Chris Johnson, Andre Ellington and core special teams player Stepfan Taylor.
