Four months after facing harsh criticism for the pock-marked playing surface at FedExField, the Redskins have made upgrades, according to a report.

The field underwent a “major renovation” and will feature a better drainage system and a cement walkway behind both teams’ benches, according to the team-owned radio station.

ESPN 980’s Chris Russell also reported via Twitter that the Redskins will re-sod the middle of the field “for the 1st time in stadium history” starting Nov. 4. After hosting the Chargers a day earlier, the Redskins do not play in Landover again until they host Colin Kaepernick and the 49ers on Monday Night Football 22 days later.

In February, GM Bruce Allen lamented not re-sodding the field during a break between games last season, saying, “Once the [2013] schedule comes out, our people are ready to commit to a schedule so we have some new sod for the end of the year. We think that is going to address the playing field in December and hopefully January.”

In that same interview, Allen said the team did not plan to consider installing an artificial surface.
