Scouts from the Bengals, along with several other teams, are in attendance at Idaho's pro day, according to Moscow Pullman Daily News' Ben Handel.
There are three main names that are likely working out at the school's pro day, punter Robert Cowan, place kicker Trey Farquhar and running back Ryan Bass.
Even though the Bengals' punter and both of their kickers are all free agents, they'll probably work to re-sign Kevin Huber and either Josh Brown or Mike Nugent. So, by the powers of deduction, the Bengals are likely in Idaho to check out Bass.
Bass transferred from Arizona State following his two seasons in 2008 and 2009. He sat out in 2010 due to NCAA transfer rules before starting up again with Idaho in 2011. In 2012, Bass led the team in rushing with 484 yards on 129 carries. Bass also returned kicks for the team.
