Both the Dallas Cowboys and San Francisco 49ers went winless in Week 1 of the 2015 NFL preseason, and one of the teams will remain without a victory after Week 2. San Francisco will host Dallas on Sunday night, as the two teams look for their first win of the year.

Dallas was missing many of their starters, including Tony Romo, when they suffered a 17-7 loss to the San Diego Chargers last week. Starting quarterback Colin Kaepernick saw limited action as the 49ers lost to the Houston Texans by 13 points.

Injury News

Dez Bryant’s hamstring injury isn’t considered to be serious, but the ailment will likely delay his 2015 debut for at least another week. Byron Jones doesn’t have any structural damage in his shoulder after getting a second opinion, but the rookie cornerback isn’t likely to play on Sunday. Tackles Tyron Smith and Doug Free could sit, as well, and right guard Zack Martin is no guarantee to play after suffering a stinger at practice. If most of the Cowboys' starting offensive linemen sit, Romo could take the week off, as well.

San Francisco linebacker NaVorro Bowman is almost completely healthy, but it’s unknown if the linebacker will make his preseason debut on Sunday. Linebacker Nick Bellore returned to the practice field this week, and Michael Wilhoite could be back soon, though he remains sidelined. Glenn Dorsey, Bruce Ellington and Philip Wheeler are dealing with injuries that aren’t considered to be serious.

Players to Watch

A year after the Cowboys had the top rusher in football, they don’t know who their No.1 running back will be just three weeks away from the regular season opener. Joseph Randle, Darren McFadden and Lance Dunbar are recovering from injuries, and none of the three players have created any separation in the competition for the starting job. Randle could miss the game with an oblique injury.

Kaepernick only attempted three passes in the preseason opener, and Sunday will mark his first extended playing time this year. The quarterback struggled last season, and he’ll see what he can do with deep-threat Torrey Smith at his disposal on Sunday.

Where to Watch

CBS 11 in Dallas and KPIX 5 in San Francisco will broadcast the game locally at 8 p.m. ET.
