The Browns announced Friday the signings of four undrafted free agents, a group that includes even more players with extensive experience and production at the college level.

Cleveland inked contracts with Northern Illinois offensive lineman Tyler Loos, Kentucky offensive lineman Darrian Miller, Tennessee State defensive back De'Ante Saunders and Oregon State defensive lineman Dylan Wynn.

The quartet of signees joined the Browns' 12 draft picks and a slew of tryout players in Berea for the first of three days of rookie mini-camp.

Loos (6-foot-5, 294 pounds) started 33 games over three seasons, earning All-MAC first-team honors in 2013 and 2014 and a second-team nod in 2012. He primarily played at left tackle for the Huskies, who rushed for 3,288 yards and allowed 11 sacks in 2014.

Miller (6-foot-5, 307 pounds) began his Kentucky career as a tight end before converting to offensive line. He was the Wildcats' starter at left tackle from 2012-2014.

Saunders (5-foot-9, 187 pounds) began his college career at Florida, where he started 16 of 20 games and intercepted three passes. In his next two seasons at Tennessee State, Saunders tallied nine interceptions, one of which he took back for a touchdown, and 15 passes defensed. He also returned 57 punts for 373 yards and a touchdown.

Wynn (6-foot-2, 283 pounds) notched 44 starts over four seasons with the Beavers, a number that was good for a tie for seventh in program history. He split time at defensive end and defensive tackle and tied for the team lead with 12 tackles for loss and four sacks as a senior.
