The Texans have agreed to terms with guard Shelley Smith on a four-year contract. Smith was a sixth round pick out of Colorado State. Houston also signed three free agents who had been brought in for tryouts: tight end Derek Fine, fullback Justin Griffith and receiver Bobby Williams.

Texans tight end Owen Daniels signed his restricted free-agent tender offer on Friday, the team announced. His one-year deal is worth $3.168 million. Daniels, who ranks second in franchise history in receptions (207) and receiving yards (2,501), missed the last eight games of the 2009 season with a torn anterior cruciate ligament.

The Texans placed veteran Ryan Moats on waivers Thursday. Moats, 27, spent the last two seasons with the Texans, starting two games last season and rushing for 390 yards and scoring four touchdowns. With second-round pick Ben Tate finally healthy, Kubiak wanted to make sure he made up for lost time and cleared space on the practice field by releasing Moats.

The Texans have four quarterbacks on their roster, but coach Gary Kubiak says that they'll trim one in the near future. Houston has starter Matt Schaub, backup Dan Orlovsky, John David Booty and rookie free agent Tyler Sheehan. "I'm trying to get a feel for Booty and take a look at Tyler also," Kubiak said. "I think we go to camp with three, maybe four, but I think it's going to be three. We'll have to make a decision between the two."
