To make room on their 90-man roster Monday, the Jets released cornerback Greg Henderson and safety Demarkus Perkins, undrafted free agents who were signed after the NFL draft.
Heaps joins Geno Smith, Ryan Fitzpatrick, Matt Simms and Bryce Petty in the Jets' quarterback mix. He played two seasons at BYU, transferred to Kansas for a year and then went to Miami. He was 6 for 12 for 51 yards in three games for the Hurricanes last season.
Copeland was signed by Dallas last year as an undrafted free agent out of LSU, but was cut before the regular season.
