The 26-year-old Louks was previously with the Kansas City Chiefs before being waived May 5 after joining them via a reserve-future contract signed Dec. 29 of last year. He also spent two weeks on the Chiefs' practice squad last year and six weeks on the Seattle Seahawks' practice squad in 2012.
The 6-foot, 200-pounder also played for the then-Boston (now Mahoning Valley) Brawlers of the Fall Experimental Football League (FXFL) last year.
Louks took a circuitous route to becoming a professional wide receiver. He began his college days at Utah, where he saw spot duty as a dual-threat quarterback, completing nine of 15 passes for 145 yards and two scores while adding 380 yards on 60 carries.
