In addition to this, 10 colleges field teams in the Collegiate Sprint Football League, a league in which all players must weigh no more than 178 pounds in order to be eligible to play; four of those teams are long-established sprint teams that co-exist alongside their NCAA counterparts (two from the Ivy League and two military academies), while six teams that have been added since the CSFL began an ongoing expansion in 2008 either never had a varsity squad (one recent addition, 2015 expansion team Chestnut Hill College, was an all-women's school that did not even admit men until 2003) or downgraded from an NCAA team to a sprint team.
