Chicago Bears running backs Chester Taylor and Kahlil Bell had to be separated during Thursday's practice, Brad Biggs of the Chicago Tribune reports.

According to Biggs, the situation was brewing for some time before escalating during yesterday's practice in the team's indoor practice facility, which is named for legendary Bears running back Walter Payton.

Taylor's third-down prowess was accompanied by a history of fisticuffs with teammates when he inked a four-year, $12.5 million contract with the Bears this off-season. Biggs notes that Taylor scraped with Erasmus James in Minnesota and Orlando Brown in Baltimore.

Taylor has 82 carries for 213 yards and a touchdown, with 14 receptions for 100 yards, for the Bears this season, but had a forgettable month of November. Despite scoring his one touchdown on the season last month, Taylor had 38 carries for 53 yards and 4 receptions for 22 yards, with no passes thrown his way over the last two weeks.

Matt Forte continues to be "The Man" in Chicago's backfield, while Bell has not been active for a game this season.
