Re: WR remains likely top pick for Texans
@AdamSchefter: Keenan Allen, the No. 1-rated WR on some boards, was red-flagged for a drug test at scouting combine in Indy and retested this month.
@AdamSchefter: Keenan Allen's agent, JT Johnson, denied his client failed any drug test. Results of recent test unknown. Some had Allen as draft's No. 1 WR
