Texans owner Bob McNair has not given coaches the green light to audition Colin Kaepernick, despite a report from Howard Balzer of Sports On Earth (Twitter link) indicating otherwise. Balzer now indicates that his tweet was intended to be a joke. Mike Florio of Pro Football Talk has confirmed that McNair has not signed off on a Kaepernick workout. The Texans have managed to stay afloat at 3-4 despite injuries to key defenders J.J. Watt and Whitney Mercilus. Asking them to keep their playoffs alive with Tom Savage under center, however, might be too much to ask. Kaepernick stands as the most polarizing figure in the football world today, so it stands to reason that the Texans may want to see what he can offer.
