San Diego, CA (Sports Network) - San Diego Chargers running back LaDainian Tomlinson is listed as doubtful for Sunday's playoff game against the Steelers.
Tomlinson, who hasn't practiced all week with a torn groin muscle, sat out the entire second half of the Chargers' overtime win over the Colts last week after aggravating the injury. He recorded 25 yards on five rushes with a touchdown against Indianapolis.
Tight end Antonio Gates is listed as questionable, as he is still dealing with a high ankle sprain. He has also sat out practice for the duration of the week after recording a team-best eight receptions for 87 yards in last week's victory.
Kicker Nate Kaeding is battling a groin injury and sat out practice the last two days. He is listed as probable, as is linebacker Brandon Siler, who missed the team's last two games with a foot issue.
