PHOENIX - Are the Baltimore Ravens likely to spend significant money on a free agent? Probably not. But head coach John Harbaugh did acknowledge Tuesday that the team is intrigued by a talented group of free agent pass rushers that includes Pro Bowler Elvis Dumervil, former NFL Defensive Player of the Year James Harrison and former Pro Bowlers Osi Umenyiora and Dwight Freeney.

The Ravens' top sacker from last season, Paul Kruger, signed with the Cleveland Browns as a free agent and Baltimore is expected to be in the market for a pass rusher to replace him, potentially through free agency if the Ravens can make it work from a financial standpoint.

"It wouldn't hurt," Harbaugh said. "We're never going to walk away from a good player, and there just happens to be some pass rushers available right now, so you've got to look at the market and what's available out there.

"Those guys are available right now, so we're looking at them. ... There [are] a lot of good pass rushers out there, guys that have done it."

Dumervil probably represents the most intriguing option considering he's just 29 years old and has 37½ sacks and 10 forced fumbles during the last three seasons.

The problem for Baltimore is that Dumervil's reportedly seeking at least $8 million per season and the Ravens have limited money to spend under the salary cap.

Harrison, the former Pittsburgh Steelers star, is another intriguing option, but he'll be 35 in May and, despite tallying five sacks during the final seven games of last season, he's viewed as an aging, injury-prone player with a significantly diminished physical skill set.

It's probably more likely the Ravens look to add a pass rusher through the NFL draft. They met with several of the top-rated pass rushers in this year's draft at the NFL Scouting Combine in February, including former Florida State standouts Tank Carradine and Brandon Jenkins, who are both expected to be selected during the second round of the draft in April.

RAVENS 'VERY OPEN' TO BRINGING McKINNIE BACK: Left tackle Bryant McKinnie has reportedly garnered only minimal interest on the free agent market and Harbaugh said Tuesday that Baltimore is "very open to bringing Bryant back."

"I hope that works out," Harbaugh said.

If McKinnie returns, Harbaugh said he'll be the Ravens' starting left tackle. If he doesn't, the Ravens will likely be forced to move Michael Oher back to left tackle, a position he struggled at last season before shifting to right tackle for the playoffs.

NO UPDATE ON McCLAIN: Harbaugh said Tuesday that injured inside linebacker Jameel McClain is still yet to receive full clearance from doctors as he continues to recover from the spinal cord contusion he suffered in December.

Regarding McClain's health, Harbaugh said: "I don't know that yet. That's a conversation we're going to have on Thursday when we get back. Jameel is in conversation with different doctors. The last he told me, he had one more doctor to see and he was very optimistic. But until he gets the clearance, you don't know."

McClain told the Carroll County Times in January that his goal is to play this season, but he admitted that, at that point, he was "just taking it slow and resting."

McClain ranked third on the Ravens in tackles (79) at the time of his injury last season. He's been a starter at inside linebacker each of the last three years and signed a two-year, $10.5 million contract with Baltimore last offseason.
