OL shuffling underway: LG Rachal gone, OT Brown added

The first change on the Bears embattled offensive line came from an unexpected direction Wednesday when guard Chilo Rachal abruptly left the team for personal reasons and was replaced on the 53-man roster by rookie undrafted free agent James Brown from the practice squad.Rachals exit points to Chris Spencer returning to the starting lineup. Spencer was demoted from the left-guard spot after the loss to Green Bay and has lately been replaced by Jonathan Scott as the extra lineman in the Bears jumbo packages.Rachal suffered through an abysmal game against the San Francisco 49ers,unofficiallyallowing a sack and QB hurry in addition to two holding penalties.Rachal signed a one-year deal last offseason and told CSNChicago.com last week that he hoped to play well enough for an extension here. He stayed after practice every day working on his hand-punch on the heavy blocking bag.Brown was a surprise find after last Aprils draft, having been expected to be selected in a market that is having increasing difficulty finding adequate supplies or and quality in offensive linemen.But the current difficulties at tackle for the Bears do not point to Brown suddenly going from the developmental squad to blocking Jared Allen.Its not like at this point of the season you can take a James Brown, whom Im very high onof course Im always high on all the players because they work so hardand say, OK, youre the guy now, offensive coordinator Mike Tice sad on Wednesday. That would be desperation.
