Reed, who spent the first 11 seasons of his career in Baltimore, will be there because the Ravens are hosting his new team, the Texans. Lewis will be there for a slightly different reason: The Ravens announced this week that they'll be inducting Lewis into the team's Ring of Honor.
Lewis will become only the sixth Ravens player to be inducted into the Ring of Honor, joining running back Jamal Lewis (2012), kicker Matt Stover (2011), tackle Jonathan Ogden (2008), outside linebacker Peter Boulware (2006) and defensive end Michael McCrary (2004).
Former Ravens owner Art Modell and eight former Baltimore Colts players are also in the Ring of Honor.
Lewis spent his entire 17-year career in Baltimore and during that time he won two Super Bowls, made 13 Pro Bowl appearances and won two Defensive Player of the Year awards (2000, 2003). He also has Brian Urlacher's endorsement as the best middle linebacker in football history.
The Ravens are also planning to erect a statue in Lewis' honor; however, that won't be ready in time for September's ceremony.
