The Texans re-signed veteran wide receiver Chris Conley to the practice squad Monday morning after releasing him twice last week.
They released veteran running back Marlon Mack.
Conley was signed to a one-year contract in the offseason. He caught 22 passes for 323 yards and two touchdowns last season.
Conley (6-foot-3, 205 pounds) has 4.35 speed in the 40-yard dash and a 45-inch vertical leap.
A former Kansas City Chiefs third-round draft pick from Georgia, Conley has 213 career receptions for 2,807 yards and 15 touchdowns.
Mack had an underwhelming preseason and lost ground in the competition with rookie running back Dameon Pierce.
That led to Mack being cut from the 53-man roster and then rejoining the Texans on their practice squad before being released Monday.
A former 1,000-yard rusher with the Indianapolis Colts who's trying to resurrect his career with the Texans, Mack showed occasional flashes of his old explosive form during the preseason. He also displayed some hesitation at times.
Mack was limited to 32 carries, and 127 yards over the past two years due to a torn Achilles tendon suffered in the first game of the 2020 season,
After rushing for a combined 1,999 yards and 17 touchdowns across 2018 and 2019, Mack made a full recovery by last year. By then, though, he was behind Jonathan Taylor, a gifted All-Pro runner who rushed for an NFL-high 1,811 yards and 17 touchdowns last season. Mack requested a trade, but nothing materialized. As a free agent, he signed a one-year, $2 million contract that included a $250,000 signing bonus to join the Texans.
