Leak, 24, has yet to play a game in the NFL since going undrafted out the University of Maryland in 2016. He spent 10 weeks on the Indianapolis Colts’ practice squad last season.
Leak played 27 games (16 starts) over three seasons with Terrapins (2011-12, 2014, red-shirt in 2013). He had 55 catches for 775 yards and six touchdowns at Maryland.
The Texans’ wide receiver position was thinned by Fuller breaking his collarbone last week. But Leak is more likely depth for camp or the practice squad than an option to see the field during the regular season for Houston.
