Baltimore Ravens coach John Harbaugh Womens Lamar Jackson Jersey , who hasn't had that many QBs on his opening day roster since 2009.Now he's got to determine the best way to use them.Joe Flacco will start Sunday against the Buffalo Bills, but Harbaugh isn't revealing whether the backup will be Robert Griffin III or rookie Lamar Jackson.Griffin has 42 games of NFL experience and Jackson is a slick-footed runner who could be a threat near the goal line, as evidenced by his three rushing touchdowns during the preseason.Whether Griffin or Jackson receives spot duty remains to be seen. At this point, Harbaugh isn't even sure how many quarterbacks will be on the active list each week."It won't be any more than three, it won't be less than two," he said with a grin on Monday. "So, we'll see. I really don't know."This much is certain: There's a lot to like about having a former Super Bowl MVP (Flacco) and a pair of Heisman Trophy winners at the most important position on the field."I'm excited to have three quality quarterbacks Womens Hayden Hurst Jersey ," Harbaugh said. "It makes our quarterback room stronger. That's really what it does."Griffin went 27 for 41 for 243 yards and two touchdowns this summer. He also proved to very helpful in guiding Jackson through his first NFL camp.Still, Harbaugh said after the preseason finale against the Washington Redskins last week that Griffin's place on the 53-man roster "depends on the rest of the math."After sitting out the Redskins game, Griffin expressed absolutely no anxiety in awaiting the Ravens' decision."When you put in the hard work and you've done everything you possibly can to put your best foot forward and try to show the team that you deserve to be here, there's no stress," he said.After the Ravens did the math, Griffin was too good to subtract from the equation."From a team standpoint, you can look at it any kind of number of different ways Cheap Marshal Yanda Jersey ," Harbaugh said. "There are a lot of factors that were considered, and that was the way it shook out."After going three years without a playoff berth, the Ravens probably can't afford to have a rookie take over if Flacco gets hurt or plays poorly over an extended period of time. Griffin went to the postseason with the Washington Redskins in 2012 and showed during the preseason he can run this offense.Though Jackson showed improvement in each of his five appearances, at this point he's still going through the learning phase. Fortunately, he has two willing teachers in Flacco and Griffin."You can never have enough experience, good guys, good people to draw on Cheap Matt Skura Jersey ," Harbaugh said. "He just learns so much from Joe and from Rob."Ravens final injury report: Tim Williams and Anthony Averett ruled OUT The Baltimore Ravens finished their final practice of the week before heading to Cleveland to face the Browns on Sunday. The Ravens have released their final injury report for this week.Baltimore has ruled out Anthony Averett (hamstring) and Tim Williams (hamstring), while Brandon Carr (knee), Willie Henry (abdomen), Hayden Hurst (foot), Anthony Levine Sr. (hamstring), Alex Lewis (shoulder), Michael Pierce (foot) Patrick Onwuasor Jersey , and Za’Darius Smith (hamstring) are questionable. Although Averett is set to miss his third game of the season, the Ravens will have help in the secondary as Jimmy Smith is expected to return following his four-game suspension. Baltimore has yet to officially place him on the active roster, but that move will happen at some point before Saturday at 4:00 pm ET. With Tim Williams ruled out for Sunday, Tyus Bowser will likely see an increase in snaps as Za’Darius Smith is also dealing with a hamstring injury. The biggest question for Baltimore is Hayden Hurst, who could make his regular season debut against the Browns. Head coach John Harbaugh stated that Hurst was close to playing last week, but the medical staff did not feel comfortable as he only had a limited amount of practice. The good news for the Ravens is that Alex Collins was removed from the injury report after missing Thursday’s practice with a knee injury.
