Spencer, an experienced punt returner from his years in the CFL, will join a Broncos team that was last in the NFL in punt-return average, Troy Renck of ABC 7 Denver reports.

The Broncos were holding onto River Cracraft at WR6 primarily because he was the most sure-handed punt returner on the squad. The team upgraded Sunday with the addition of Spencer who -- along with ranking seventh in the league this preseason with 103 punt-return yards on seven tries -- also recorded a 35-yard kick return. On offense, he caught four passes for 39 yards and added 48 yards on two runs. He should be active each game as a punt returner and and maybe also a kick returner, while his 4.3-speed could be featured on some gadget-type plays.
