The Baltimore Ravens took their practice outdoors today to prepare for the freezing temperatures expected in their upcoming playoff game against the Houston Texans. However, they were still without cornerback Marlon Humphrey, who has been dealing with a calf injury. Humphrey has not practiced since injuring his calf against the Miami Dolphins.

Humphrey has had a history of injuries this season, missing several games due to various ailments. He has been in and out of the lineup, and his availability for Saturday's game is uncertain. While he is a veteran who could potentially miss practice all week and still play, a calf injury may require some limited work for him to be ready.

If Humphrey is unable to play, it would be his eighth missed game of the season. This would be a blow to the Ravens' defense, as Humphrey is an important piece of their secondary. However, the team has had success without him before, defeating the Texans earlier in the season without his presence.

The Ravens had some positive injury updates, with tight end Mark Andrews participating in full practice for the first time and other players returning to full practice as well. But the absence of Humphrey remains the biggest question mark for the Ravens' defense heading into the Divisional Round matchup.

In the meantime, the Texans' defense is dealing with their own injury concerns, as defensive ends Jonathan Greenard and Will Anderson Jr. did not practice due to ankle injuries.

Overall, the status of Marlon Humphrey will be closely watched as the Ravens prepare for their playoff game against the Texans.
