(This is the fourth part in a series that spotlights five 49ers players to watch in the team's exhibition game Saturday, 5 p.m., at the Houston Texans.)

The No. 3 player to watch is a rookie wide receiver who will be on the 53-man roster. The No. 2 player to watch is a rookie wide receiver who could be auditioning for another team's 53-man roster.Chris Owusu made a triumphant and mostly under-the-radar return to football in the exhibition opener. He led the 49ers with three catches for 35 yards in his first game since seeing his final season at Stanford cut short due to concussions.He caught two passes near the sideline and cut back inside to pick up extra yards. The 49ers even lined him up at gunner on punt coverage, and he looked good in that role, too.Interestingly, Owusu has been a forgotten man among the 49ers' receivers. He has seen the least practice action of any of the 49ers' undrafted rookie widouts -- a group that includes Nathan Palmer and Brian Tyms.When he gets on the field, Owusu has looked good. There is no denying his talent.He ran faster than the 49ers' top two picks, A.J. Jenkins and LaMichael James, at the NFL scouting combine. Despite ranking among the best kick returners in Pac-12 history, Owusu has gotten no practice work in that craft.He went undrafted due to his concussion history. The 49ers signed him, and he could be ticketed for a spot on the practice squad.That is, unless he plays so well that another team pounces on him after the final cuts.
