Darrius Heyward-Bey injury: Raiders WR back practicing

Oakland Raiders wide receiver Darrius Heyward-Bey was back at practice on Tuesday after being knocked out of the team's Week 3 34-31 victory over the Pittsburgh Steelers with a scary helmet-to-helmet collision, CSN Bay Area reports.

Heyward-Bey missed Sunday's game against the Denver Broncos because of a concussion and neck strain suffered in the hit delivered by Ryan Mundy. He was knocked so hard that Heyward-Bey doesn't even remember the hit.

Heyward-Bey has nine receptions for 98 yards and one touchdown on the year. He had two receptions for 14 yards and a touchdown before being knocked out of the game against the Steelers.

He took part in the first team-offense stretches and drills on Tuesday, and will most likely practice tomorrow. The Raiders won't practice again until next Monday due to a CBA-mandated break. The Raiders have a bye-week in Week 5 and then go on the road to face the Atlanta Falcons in Week 6.
