Following the significant losses of players due to injury and illness, including Brandon Aiyuk, San Francisco 49ers head coach Kyle Shanahan said he will "look into everything" on the trade market to address the wide receiver position.

"We try to look into everything regardless," Shanahan told reporters on Monday. "Obviously with more issues that came up yesterday, you still want to look into everything, but it has to do with what options are out there with stuff that we can pull off that doesn't totally hurt us, that helps us now and doesn't hurt us for the future."

The 49ers lost Brandon Aiyuk to a torn ACL and MCL, Deebo Samuel was hospitalized with pneumonia on Monday and Jauan Jennings was notably absent during Sunday's loss to the Kansas City Chiefs due to a hip injury.

The 49ers currently have 18 players listed as questionable, out, or on injured reserve from their 53-man roster, accounting for roughly 34 percent of the team.

This has forced Shanahan and the front office to start making moves if the 49ers hope to make a push for the postseason.

"There's lots of decisions that go into it," Shannahan told reporters. "So, we'll look into everything, but a lot of times that's just kind of living in hope. Those answers aren't always out there. You've got to be ready to get people better in your building and deal with what you've got in your building. And if you ever find something that makes sense, we will never hesitate on it but it's not always available like you hope it is."

Davante Adams and Amarai Cooper are off the list after the two WR's were traded last week. However, DeAndre Hopkins and Mike Williams could be on the table.
