Although Ravens left tackle Eugene Monroe said his arthroscopic knee surgery went well last week, he was noncommittal on when he'll return to practice.
Monroe declined to say if he completely tore or partially tore his meniscus and said he has no timetable on when he'll be able to run again.
Monroe is expected to miss roughly a month, according to a source.
"It just depends," Monroe said. "I'm doing everything I can to get back as soon as it's possible. I just come in and work every day to get healthy."
Monroe barely made it through the Ravens' 23-21 win over the Cleveland Browns, limping back to the huddle each play. He was replaced in the starting lineup last Sunday by undrafted rookie James Hurst, who helped the Ravens to a 38-10 win over the Carolina Panthers.
"I toughed it out, but I've dealt with injuries throughout my career before," Monroe said. "Nothing like this in the middle of the season, but I'm working to get back."
Monroe praised the work of Hurst, a former all-conference selection at North Carolina.
"I was confident he would do just what he did," Monroe said. "He works his butt off. He has talent. I don't know how he went undrafted. I expect him to continue to keep it up."
The Ravens haven't allowed a sack in three consecutive games.
"When you dominate people, you can do that," Monroe said. "It shows up on film. We've been extremely physical every game. So, we just need to continue that trend."
