The Houston Texans have extended the contract of cornerback Aaron Glenn, the former Texas A&M star taken from the New York Jets in the spring expansion draft. Glenn, in his ninth NFL season, made the Pro Bowl in 1997 and 1998 with New York. He leads the Texans with two interceptions and five passes defensed this year. Glenn was in the final year of a contract he had signed with the Jets which carried over to the Texans when he was selected in the expansion draft.
