The Texans have placed EDGE Jonathan Greenard on IR with the calf injury he suffered in practice this week. He had already been ruled out for Sunday's game against the Raiders. This means he'll miss at least the following 3 games as well. ESPN's Adam Schefter reports that Greenard is expected to miss 4-6 weeks. His absence should mean more playing time for veteran Mario Addison; perhaps starter Rasheem Green as well. Green's weekly snap shares have gone: 54%, 57%, 53% and 61%.
