The Buffalo Bills need healthy bodies on their 53-man roster, so they turned to the practice squad Tuesday.
The team promoted wide receiver Dez Lewis and defensive tackle Deandre Coleman to the active roster. They replace receiver Walt Powell and defensive tackle Corbin Bryant, both of whom were placed on injured reserve.
Powell suffered an ankle injury in Sunday's 28-21 victory over the Jacksonville Jaguars, while Bryant has missed the past three games because of a shoulder injury.
Coleman, 6-foot-5 and 341 pounds, has five games over the past two NFL seasons with the Miami Dolphins. He originally entered the NFL as an undrafted free agent with the Jacksonville Jaguars in 2014 after his college career at Cal.
Lewis, 6-4 and 214 pounds, has spent most of the past two seasons on the practice squad after being drafted in the seventh round by the Bills in 2014. He appeared in one game last season after getting called up to the active roster, but did not record any statistics. Lewis has a strong spring, but wasn't able to crack the 53-man roster at the end of training camp.
With two vacancies on the practice squad, the team re-signed tight end Gerald Christian. He has bounced between the practice squad and 53-man roster, from which he was released last week.
